One hundred and eighty five samples of red, white and rosé wines and different juices purchased in Entre Rios, Argentina, were analyzed for the Alternaria mycotoxins alternariol (AOH) and alternariol methyl ether (AME). White wines were analyzed after removal of alcohol by a nitrogen stream and concentrated. AOH in red wines was cleaned up by solid-phase… (More)
We examined the relationship between nocturnal respiratory disturbance and learning and compared learning in children with and without nocturnal respiratory disturbance. Subjects were 149 participants in a prospective cohort study examining sleep in children ages 6-12: The Tucson Children's Assessment of Sleep Apnea study (TuCASA). Sleep was assessed via… (More)
The antileishmanial efficacy of four novel quinoline derivatives was determined in vitro against Leishmania chagasi, using extracellular and intracellular parasite models. When tested against L. chagasi-infected macrophages, compound 3b demonstrated 8.3-fold greater activity than did the standard pentavalent antimony. No significant activity was found for… (More)
The 6.7-MeV, 100-mA proton beam being produced in the Low Energy Demonstration Accelerator (LEDA) RFQ will be injected into a 52-magnet lattice in order to study the formation of beam halo . The LEDA RFQ beam has a rms size of 1 mm. At nine longitudinal locations along the lattice an assembly that incorporates both a wire scanner and a halo-scraper… (More)
Dispersion strengthened copper, known by the trade name GLIDCOP , has found various applications in accelerator designs. Glidcop has material properties similar to OFE copper, such as thermal and electrical conductivity. Unlike OFE, however, Glidcop has yield and ultimate strengths equivalent to those of mild-carbon steel, making it a good structural… (More)
Mouse peritoneal and alveolar macrophages were interacted in vitro with C. parvum oocysts and cultured in normal medium and in medium with IFN-gamma. The results showed that in vitro activation of macrophages by IFN-gamma limits C. parvum development although the inhibitory effect is not as potent as in other intracellular parasitic protozoa.
We have physically separated cochlear and vestibular end organs, and after injecting horseradish peroxidase two different populations of efferent somas have been described belonging to the cochlea and vestibule.
